Answer;
-Condensation
Step-by-step explanation;
-Condensation reaction is a reaction that takes place when two molecules join together forming a larger molecule and also produces another smaller molecule in the process. The smaller molecule produced in the reaction is normally water, however, it can also be methanol, hydrogen chloride, among other small molecules.
-Condensation is common in many biological and chemical processes such as formation of disaccharides, and polmerization reactions, where small molecules join to form a larger molecule called a polmer.
